Ultra-cold mini twisters are a strong indication of superfluidity. But they can also be key to new and powerful measuring tools. "Illustration of the density distribution of a rotating dipolar Bose-Einstein-Condensate (dBEC) exhibiting quantized vortices based on simulation data from the paper". "The vortices, visible via their density dips in the dBEC, arrange in stripes due to the anisotropic. And long-range character of the dipolar interactions between the atoms. Credit: Ella Maru Studio" (ScitechDaily.com/Ultra-Cold Mini Twisters: Quantum Vortices Are a Strong Indication of Superfluidity) Rotating bi-polar Bose-Einstein-Condensate can form a quantum twister between those particles. The Bose-Einstein-Condensate can hover above the liquid helium. And that thing can be one of the most interesting things in the quantum world. Those two pieces of Bose-Einstein-Condensate (BEC) can use to form quantum tweezers. When the BEC bites are hovering above liquid helium th...
